Summary
This earth dam stands at a height of 20 feet and has a length of 800 feet, providing a storage capacity of 161 acre-feet and serving a drainage area of 0.46 square miles along the TR-Tehuacana Creek.
Managed by the Texas Commission on Environmental Quality (TCEQ), this dam is state-regulated and inspected to ensure its safety and effectiveness in flood mitigation. Despite being classified as high risk, with a hazard potential of "Not Available", the condition of the dam is currently not rated. With no spillway and one outlet gate, the Tehuacana Creek Watershed NRCS Gcc 101 Dam plays a crucial role in managing water resources and mitigating flood risks in the region.
This dam, under the jurisdiction of the Fort Worth District of the US Army Corps of Engineers, highlights the collaborative efforts between local government and federal agencies in safeguarding communities from potential flood hazards. With its strategic location and design features, the Tehuacana Creek Watershed NRCS Gcc 101 Dam serves as a vital infrastructure for water resource management and climate resilience in the area.

Dam Data Reference
Condition Assessment
SatisfactoryNo existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
Fair
No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
Poor A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency. Investigations and studies are necessary.
Unsatisfactory
A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
Not Rated
The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
Significant
Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environment damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
Low
Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
Undetermined
Dams for which a downstream hazard potential has not been designated or is not provided.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
